CBSE NCERT Class 10 Maths Chapter 13

In NCERT Class 10 Maths Chapter 13 – Surface Areas and Volumes, you will be mainly focusing on surface areas and volumes of cone, cuboid, cube and cylinder. Some of the important topics covered in this Chapter have been discussed below.

  • Combination of Solids
  • Surface Area of a Combination of Solids

In NCERT Class 10 Maths Chapter 13 – Surface Areas and Volumes, you will learn how to break down a solid and analyse its shape in an easy way. You will also learn how to find the areas of the unknown shapes with known shapes. 

  • The Volume of Combined Solids

In this segment of NCERT Solutions for Class 10th Maths Chapter 13 – Surface Areas and Volumes, you will be learning how to find the volumes of complex objects with visualising shapes in a simplified way. The formula for calculating the volume of combined solids has been given below

The volume of combined solids

V(solid) = V(Cone) + V(hemisphere)

  • Cuboid and Surface Area

In this part of NCERT Solutions for Class 10th Maths Chapter 13 – Surface Areas and Volumes, you will be taught how to find out the surface area of a cuboid. You will also understand how it is equal to the sum of the areas of its six rectangular faces. The formula for finding the surface area of a cuboid has been given below.

cuboid = 2(l×b)+2(b×h)+2(l×h)=2(lb+bh+lh)

In this chapter, you will also learn about the cube and its surface area, cylinder and its surface area, right circular cone and its surface area and sphere and it’s surface area. 

  • Volume of Cube

Here, in CBSE Class 10 Maths Syllabus, you will learn that all the dimensions of the cube are identical.

Hence, volume = l3

Here, l is the length of the cube of the edge 

The volume of a cube = base area×height

  • Volume of Cuboid

This section of the Chapter will teach you in detail about how to calculate the volume of a cuboid. The formula for the same has been given below.

Volume of a cuboid =(base area)×height=(lb)h=lbh

  • Volume of Cylinder

This part of the Chapter deals with learning how to calculate the volume of a cylinder, the formula for which has been given below.

Volume of a cylinder = Base area × its height = (π×r2)×h=πr2h

In subsequent parts of Class 10 Maths Surface Areas and Volumes, you will also learn about the volume of a right circular cone, the volume of a sphere, the volume of a hemisphere, and hemisphere and it’s surface area. 

  • Frustum of a Cone

Here in CBSE NCERT Class 10 Maths Chapter 13, you will be learning how a plane parallel to base cuts the cone, which is why a cone has two separate parts and which part is called the frustum of a cone. You will also learn to calculate the surface area of a frustum and volume of the frustum. 

  • Shape Conversion of Solids

In this segment of NCERT Solutions for Class 10 Maths Chapter 13-Surface Areas and Volumes, you will be learning how one solid is converted into another solid with a different shape either by casting or melting with volume at a constant position.
